Description
Technical field
The utility model relates to the connection device in the video signal transmission field, particularly a kind of waterproof video cables connector.
Background technology
For guaranteeing the video signal transmission effect, in the video signal transmission process, generally video cables need be inserted in the accepting device reliably by connector, need the connector waterproof reliable simultaneously.In the prior art, the video cables connector mainly comprises nut, lining core, housing, cutting ferrule, and nut is inserted in from lining core rear portion, and the housing front end is pressed into the anterior nut that stops of lining core and withdraws from from the rear portion, penetrated cutting ferrule in the housing, and the cutting ferrule part is stretched out from the housing afterbody.The video cables inner core penetrates the lining in-core from the rear portion, cable sheath penetrates between lining core and the cutting ferrule, compressing cutting ferrule afterbody, cutting ferrule is pressed in the housing, cutting ferrule distortion back interlocking cable sheath is fixed thereby reach the video cables relative position to the lining core, and nut front screws in external equipment.
The video cables connector of this kind structure, cutting ferrule generally uses plastics manufacturing, loss of properties on aging, after a period of time, video cables and connector position are prone to loosening, well waterproof, and come the interlocking cable sheath to front portion compressing cutting ferrule, the structural reliability of connector is poor.
The utility model content
The utility model provides a kind of waterproof video cables connector reliable, that water resistance is good, stretching resistance is strong that connects at the problem that prior art exists, and is intended to improve water resistance and the reliability at video cables connector place.
Order of the present utility model is to realize like this, a kind of waterproof video cables connector, comprise nut, housing and lining core, described lining core comprises big footpath section, middle footpath section and path section, described big footpath section is provided with the housing limited step and is contained in the interior boss of described nut, footpath section and path section stretch in the described housing in described, the front port internal diameter of described housing and described in the setting that is complementary of the external diameter of footpath section, the front end face of housing is resisted against on the housing limited step of big footpath section, footpath section circumferentially is distributed with some first groove that blocks water in described, and the afterbody of described path section is provided with some pawls; Described housing periphery also is set with lock housing, and the periphery of described lock housing also is set with overcoat; The afterbody of described lock housing extends beyond the housing afterbody, and inwall also is provided with for the compressing housing to enterolithic inner conical surface; Also be provided with the lock housing limited step on the periphery wall of described housing, the rear portion of lock housing limited step and being positioned at also is provided with some second groove that blocks water on the periphery wall of described housing.
When the utility model is installed and used, at first the video cables termination is cut to internal layer annular successively by skin, making it be stairstepping from inside to outside distributes, the cored wire conductor of video cables is axially inserted the lining in-core together with insulating barrier, guarantee between lining core path section insertion insulating barrier and the cable sheath, make cable sheath enter housing and the annular gap of lining between the core, after video cables is in place, axially push the lock housing limited step of lock housing on the housing periphery wall forward, the inner conical surface of lock-shell lining will be oppressed housing to internal strain in this process, cable sheath is embedded in the pawl of lining core path section by the housing distortion compressing, and the video cables position is fixed.Compared with prior art, the beneficial effects of the utility model are, are equipped with the many places groove that blocks water between the middle footpath section of lining core and housing stitching surface, lock housing and the housing stitching surface, effectively stop rainwater to enter the video cables head, have favorable waterproof property; The path section of lining core is provided with some pawls, and the inner conical surface compressing housing of lock-shell lining embeds in the pawl cable sheath to internal strain, the connection reliability height, and the stretch-proof ability is strong.
As further improvement of the utility model, the afterbody periphery wall of described housing offers and subtracts the wall groove, describedly subtracts the wall groove ringwise.The housing afterbody that is arranged so that subtracts the wall groove on the housing easily inwardly deforms, and avoids the distortion of housing fold, and powerful effectively compressing cable sheath guarantees connection reliability.
As further improvement of the utility model, the front inner wall of described lock housing with described subtract the wall groove corresponding be provided with arc convex.During non-working condition, arc convex is in subtracts in the wall groove, when installing and using, arc convex has reduced the contact-making surface between lock-shell lining and the housing periphery wall, has reduced the force of sliding friction when lock housing is installed accordingly, makes installation more convenient quick.
As further improvement of the utility model, the front port inwall of described lock housing also offers the guiding conical surface, and the described guiding conical surface extends inwardly to described arc convex.The setting of the guiding conical surface is convenient to housing and is press-fitted in the lock housing, has housing guide effect is installed.
As further improvement of the utility model, the tapered contraction of path section tail end of described lining core.Taper is shunk the convenient lining of project organization core path section and is inserted between insulating barrier and the cable sheath.
